If you want to store it yourself APMEX.
If you want it stored for you ABX.
In near future look for Kinesis as you will be able to earn income while holding on to allocated gold.
IMHO, it is best to diversify among these options.
During a crisis you may have to protect your gold holdings – especially when people get wind that you have a lot – say Kg bars which may be hard to carry around.
With that much Gold/Silver it is best to have it professionally stored and protected. You just have to find people you trust. For me it is ABX.
To each his own.
BTW, when is this so called Mad Max level crisis set to begin? It seems to never happen and yet there is this whole fear industry…
